SPECIFICATION forming part of Letters Patent No. 352,042, dated November 2, 1886.

Application filed November 24, 1885. Serial o. 183,880. (No model.)

.To all whom it may concern:

Be it known that l, THOMAS W. CORBY, of

i GrossePointe, in thecountyof Wayne and State of Michigan, have invented anew and useful Improvementin Brick-Molds, of which the following is a specification.

My invention consists in an improvementin lbrick-molds, hereinafter fully pointed out in theclaims. v l Figure 1 is a side` elevation of a mold adapted to form six bricks, one-half thereofv being ening the movable plates to the frame. 8 is a detail view showing the interlocking of 25 the side and end mold-linings.

, A represents a rectangular frame, long and deep enough lto be divided into six compartments, each of the proper size to lform a brickmold. VOf course the frame may be larger or smaller at will 5 but I have chosen a six-mold L L represent five `partitions secured to the sides of frame A, and, with` the ends-of said frame, divide the frame into six equal vcornpartments, each a little larger than is necessary to mold a brick.

b` b c c representthin iron plates, which line the sides and ends of each compartment Or mold, the plates b b extending across the opening in Vframe A, and the plates@ o extending inglobked to the plate-b bin each vcompartment by meansof the lugs l, Fig. 8, formed onV the upper corners of each plate c, and extend-4 ing into holes formed in the edges of plates b b. B representsan iron frame of the same size as frame A, and adaptedto lie on topof frame A. Each platee is made deeper thanframe A7 and is secured to the frame B, either by a pin, k, passing through an offset in frame .B into plate c, as shown in Fig. 7, or in any other convenient manner.

Fig. 3 is au enlarged view, similar' Fig. l

K K represent bottoms, either of wood or metal, securedineach mold, being fastened to frame A at the corners o f each compartment, the plate cbeing cut away at each` end to per- Vmit this, as shown in Figs. 1 and 3.

H H represent `bars running acrossframe B, and secured thereto above the center of each 'compartment or mold in. frame A, and to each bar H is secured a block, I, which fits into a' hole formed in the bottom K, so as to form a portion of said bottom when the frame B is down on framel A. e

D D vrepresent fourcams, one Of Which is pivoted to frame A, near each corner, by a pin, a, said pin being rigid with the cam, and also rigid with bail, C, which connects the opposite pin-s a. The cams D lie under thek frame B, so that when said cams are moved they will raise or lower said franieB.

E E represent stirrups, one of which is secured to each bailv C, passing over the bottom offramelA to limit the vmotion of bail C when returned to its normal position.

FF represent smaller bails, Vone on each bail4 C, to afford hand-holds to operate bails C C; and G Grepresent springs which are fastened `tothe ends of frame A and operate as springcatches, engagingwith bails F F and holding bails O C in their normal position.

Irprefer to make the partitions L L beveled on both sides, so that they will be thinner at the bottom of .frame A vthan at the top,and to provide lthe upper edges on plates b b with outwardly-turned angesfas shown in Fig. 6, to bear against said partitions.

d d represent Yscrews or bolts which fasten g the bottomsK K to frame A. Y

Y In the arrangement Ashown in Figs. 4 and 5 the partitions LL are omitted and the ends of plates b b are dovetailed loosely into the sides offrame A, the dovetail on the' plates b being represented by t' and in the frame by g. The

vplate b which lies against the. end Wall of frame A need .not be dovetailed, but may simply extend intoal groove in the frame, as

shown ath, Fig. v,5. When this arrangement isusedLII prefer to make the frame A deep enough to mold a brick edgewise and place the plates b rbat such distances apart as to form molds to make brick on edge, in which manner a greater number of bricks can be molded in a frame of given length.v

ICO

The operation of my invention is as follows: The fra-me A, with the frame B lying close along its lower edge, is placed in a brick-machine of any known type which works with molds, and clay is fed into the molds in the frame and pressed therein in the ordinary manner until all the molds in the frame are filled and the clay properly pressed therein. The frame A is then removed from the machine, the hails C F affording convenient means for lifting it, and carried to the place where the bricks are to be hacked. The frame A is then turned overso that its open side is downward, and the hails GC are drawn up into the position shown in Figs. l and 3. This is readily done by first turning the hails F F into a Vertical position,so as to disengage them from the spring-catch G, and then pulling on said hails F F. As hails CC turn up the cams D D turn with said hails and force the frame B away from the frame A, as shown in Fig. 3, and as the plates c c are fastened to the frame B by the pins K, and the plates b b to the plates c c by the lugs Z, the plates b I) c e in each mold are drawn out from the mold, thus enlarging the mold on all sides, and permitting the brick to drop out easily. And by bevelingthe partitions L L, as shown in Fig. 6, the operation of withdrawing the plates is facilitated, because the plates b b, as they move, `recede from the sides of the brick in an obvious manner. As the barsH are fastened to frame B and the blocks I to the bars H, the motion of frame B will cause bars H. to lift the blocks I out from their position in the bottoms of the molds,th us lessening the bottom surface to which the moist bricks can adhere, and also admitting air freely into the molds, and preventing any tendency to the formation of a vacuum therein as the bricks fall out. As the hails C C turn up to the proper position in which the plates b b c c are vsufficiently withdrawn from the molds, the stirrups E E come in contact with frame B, as shown in Fig. 3, and cheek the movement of hails C C, thus preventing the complete withdrawal of plates b b c c from the molds or their withdrawal to such au extent as to break the bottoms K out of the molds.

It is evident that certain structural changes, such as fastening the cams D to the hails Gand allowing both to turn freely, pins a, &c., may be substituted for the construction shown.

The operation of the modification shown in Figs. 4 and 5 is as above described, but the partitions L L are not used.

lVhat I claim as my invention, and desire to secure by Letters Patent, is-

1. A brick-mold consisting of a series of compartments, each having removable plates on its sides and ends, and means, as specified, for locking said plates in place and for withdrawing them to permit the removal of the bricks, substantially as described.

2. Abrick-mold consisting of a frame di'- vided by partitions to form a series of compartments, removable side and end plates located within said compartments, a second frame lying on the first and connected with said removable side and end plates, and means for locking said parts together and for removing said plates with the second frame to allow the molds to be emptied, substantially as described.

3. The combination,with the frame A, having partitions L L and bottoms K K, of the frame B, the side plates, b b, and end plates, cc, secured to said frame B and removably located within the compartments of the frame A, and the earns D D, pivoted to said frame A and adapted to operate upon the frame B to remove the attached side and end plates prior to emptying the molds, substantially as described.

4. The combination,with the frame A, having a series of compartments, of the frame B, provided with attached plates I) I) and c c, removably located within said compartments, and the cams D D and bails C F, pivoted to the frame A and acting upon the frame B, whereby said frame B and attached plates are removed to empty the molds, suhstantially'as described.

5. In combination with the frame A, a series of compartments provided with bottoms K, each having a portion thereof cut away, the frame B, bars H, secured to said frame, and blocks I, secured to said bars, substantially as shown and described.

6. In combination with the frame A,having stationary beveled partitions L and bottoms K, the frame B, and the movable side plates, b b, and end plates, c c, resting against said partitions L and secured to said frame B, substantially as shown and described.

7. In combination with the frame B, the plates c, secured thereto and having thereon the lugs l, and the plates b, having notches therein to receive said lugs, the frame A,-pro vided with a series of compartments to receive the plates b c, and means for securing and detaching said frames, substantially as shown and described.

8. In combination with the frame A,having the spring-catch G thereon, the frame B, hails G and cams D, pivoted to frame A, and the bails F, pivoted on bails C and engaging with spring-catches G, substantially as shown and described.
